On Sunday, the Denver Broncos will face one of the most dangerous quarterbacks of all-time in the Patriots’ Tom Brady.

The Broncos will do that, though, without one of their best defensive backs. Cornerback Chris Harris sustained a torn ACL against the Chargers and is done for the foreseeable future. USA Today was the first to report the news.

His absence is no small factor. Champ Bailey has been slowed all year long and Quentin Jammer hasn’t been the impact player he once was. The most reliable player in the Broncos’ secondary is Harris.

The Patriots defeated the Indianapolis Colts without Brady throwing a single touchdown pass. Still, Julian Edelman and Danny Amendola can hurt the Broncos. New England went often to running back LeGarrette Blount—who scored four touchdowns in the win—and they will likely do the same this week.

But if Brady wanted to air it out, his chances against a depleted Broncos’ secondary are probably better than good.
